[0028] REFERENCE Figures 1-5The embodiment of the utility model discloses a kind of delivery systems, for being delivered to seabed including but not limited to marine detection system such as OBS, OBEM or marine engineering construction equipment (such as cement block) etc. The delivery system includes fixed frame 1 and release mechanism 2, fixed frame 1 can be connected with cableway etc. hoisting equipment on mother ship, release mechanism 2 is arranged on fixed frame 1, release mechanism 2 includes releaser 21, connecting rope 22, first lever 23 and second lever 24, wherein releaser 21 is arranged on fixed frame 1, releaser 21 clamps the first end of connecting rope 22, first lever 23 is hinged to fixed frame 1 by first hinged shaft, the second end of connecting rope 22 is connected with the first end of first lever 23, and can provide upward tension to the first end of first lever 23, second lever 24 is hinged to fixed frame 1 by second hinged shaft, the second end of first lever 23 is overlapped on the first end top surface of second lever 24, the second end of second lever 24 is slidably sleeved with connecting piece 27, connecting piece 27 can be separated from second lever 24, and connecting piece 27 is used to connect the equipment to be delivered. It needs to be emphasized that first lever 23 and second lever 24 are all non-effort lever, and at least one of first lever 23 and second lever 24 is effort lever.
[0029] The delivery system utilizes lever principle, connecting rope 22 connects releaser 21 and first lever 23, first lever 23 is overlapped on second lever 24, when releaser 21 releases connecting rope 22, the first end of first lever 23 loses the upward tension exerted by connecting rope 22, the first end of second lever 24 loses the pressing action of the second end of first lever 23, under the action of the gravity of the equipment to be delivered, the second end of second lever 24 overturns downward, so that connecting piece 27 slides downward and separates from second lever 24, realizing the separation of the equipment to be delivered and the delivery system. The application of at least one of first lever 23 and second lever 24 as effort lever reduces the weight of the load required by releaser 21, so that the delivery system can be used to deliver the equipment to be delivered with larger mass.
[0030] In the embodiment, first lever 23 and second lever 24 are both effort lever, at this time, the weight of the load required by releaser 21 is minimum, which is beneficial to prolong the service life of releaser 21.
[0031] Reference Figure 1As shown, the fixed frame 1 comprises a crossbeam, a longitudinal beam, a vertical beam and a base, wherein the base is provided as a rectangular frame structure, the base is formed with a through opening for the launched device to pass through, the longitudinal beam and the crossbeam are provided in a cross shape, the four vertical beams are arranged perpendicularly to the four sides of the base and are respectively connected to the ends of the longitudinal beam and the crossbeam, the release device 21 is arranged in one of the vertical beams, and the first lever 23 and the second lever 24 are hinged to the crossbeam. Specifically, the fixed frame 1 is made of stainless steel material, and the outer surface is passivated to improve the seawater corrosion resistance, and the release device 21 is an acoustic release device.
[0032] Referring to Figure 2 As shown, the connecting piece 27 comprises a connecting ring and a shackle, the connecting ring is a closed ring and is sleeved on the second lever 24 to improve the stability when the connecting piece 27 is sleeved on the second lever 24, and the shackle is an open ring and is used to connect the launched device to facilitate disassembly of the launched device, and the connecting ring and the shackle are connected by a connecting rod.
[0033] Referring to Figure 3 As shown, the release mechanism 2 further comprises a first fixed pulley 25 and a second fixed pulley 26, the first fixed pulley 25 is located below the release device 21, and the second fixed pulley 26 is located on one side of the release device 21, i.e. the second fixed pulley 26 is located above the first fixed pulley 25, and the connecting rope 22 is connected to the first lever 23 after being wound around the first fixed pulley 25 and the second fixed pulley 26 in sequence, thereby reducing the occupied space of the launching system in the height direction.
[0034] During the lowering process of the launched device with the launching system, there may be a situation that the lowering speed is inconsistent with the sinking speed, or the launched device is affected by the water flow and uneven distribution of its own gravity, resulting in shaking and tilting of the launched device. Taking the OBEM and the OBS as examples, both of them are provided with a floating ball, and the weight in water is greatly reduced compared with the weight in air. Through actual measurement, it is found that the sinking speed of the OBEM and the OBS in water is 25-30 m / min, and the winch on the mother ship generally releases the cable at a speed of 50 m / min. In order to prevent the launching system from repeatedly impacting the launched device during the sinking process, the launching system further comprises a limiting mechanism 3, and the limiting mechanism 3 comprises a plurality of limiting plates 31, which are installed on the inner wall of the through opening in a circumferential direction and are elastically connected to the base by elastic members 32. The plurality of limiting plates 31 form a limiting space for limiting the launched device. During the lowering process, the launched device is clamped by the limiting mechanism 3, so as to keep stable relative to the fixed frame 1, thereby reducing the impact with the fixed frame 1 and the shaking of the launched device.
[0035] Specifically, the elastic member 32 is a spring. It can be understood that according to the size of the launched device, the length of the spring can be replaced according to the actual situation.
[0036] Due to the complex seafloor micro-topography, the release system can be tilted unpredictably, causing the change of the vector direction, which seriously affects the authenticity and reliability of the signals and data collected by the released equipment on the seafloor. Moreover, the seafloor bottom of the deep sea is generally deep-sea clay, which is soft and strongly adhesive, and the released equipment can be trapped in the clay, and the release device 21 can be wrapped in clay, causing the released equipment to be unable to be released. On this basis, the release system further comprises an image acquisition unit and a controller 7, the image acquisition unit is used to acquire relevant image information and is in communication connection with the controller 7, and the controller 7 can upload the data of the image acquisition unit to the deck unit of the mother ship, so that the staff on the deck can observe the seafloor topography and bottom conditions around the release system in real time, and when it is confirmed that the seafloor topography can meet the release requirements, the released equipment is released again.
[0037] Specifically, the controller 7 comprises a control unit, an optical and electrical composite cable connected with the control unit and the deck unit, a junction box 8 connected with the optical and electrical composite cable and used for optical and electrical separation, a transformer 10 used for converting 220V AC into 24V DC, 5V DC and other voltages for transmitting the optical and electrical composite cable to the underwater, and a compensator 9 used for keeping the pressure in the junction box 8 substantially consistent with the pressure of the near-seafloor environment.
[0038] More specifically, the optical and electrical composite cable is fixed to the top of the fixed frame 1 through a cable end connector 40, the control unit adopts RS232 and RS485 serial ports, the communication protocol adopts asynchronous serial communication protocol, 8-bit data, 1-bit stop bit, no parity bit, and the baud rate is 9600bps. The junction box 8 comprises four interfaces, which are an optical and electrical mixed input interface, an oil pressure compensation interface, an optical fiber interface and a low-voltage output interface. The optical and electrical mixed input interface is connected with the optical and electrical composite cable, and through internal optical and electrical separation, the optical signal is separated and connected to the control unit through the optical fiber interface, and the electrical signal is separated and connected to the release mechanism 2 and the image acquisition unit through the low-voltage output interface.
[0039] In this embodiment, the image acquisition unit comprises three groups of cameras 4, two groups of which are arranged on the cross beam or the longitudinal beam, and the other group is arranged on the base. One group of the two groups of cameras 4 arranged on the cross beam or the longitudinal beam looks downward for collecting image information of the release mechanism 2, so that the staff can judge whether the release mechanism 2 releases the released equipment smoothly, and the other group looks upward for collecting image information of the optical and electrical composite cable, so that the staff can observe and prevent the optical and electrical composite cable from being wound and hung on the cable end connector 40, causing damage to the optical and electrical composite cable and communication interruption. The camera 4 arranged on the base looks downward for collecting image information of the seafloor topography and bottom conditions, and judging the height from the bottom.
[0040] Since the fixed frame 1 is made of stainless steel, the contrast between the stainless steel and seawater is not obvious during the camera 4 shooting process, and the outline can only be seen when it is very close to the water surface. Therefore, the fixed frame 1 is coated with a coating to form a contrast with seawater. For example, the outer layer of the fixed frame 1 is coated with orange polyurethane paint and bio-resistant coating.
[0041] Considering the visibility of the seabed, the launching system further comprises a lighting lamp 6 corresponding to the camera 4, which provides lighting for the camera 4 and facilitates image acquisition. Specifically, the camera 4 and the lighting lamp 6 are fixed to the fixed frame 1 by a throat clamp, and the camera 4 and the lighting lamp 6 are spaced apart by 10 cm to avoid the lighting lamp 6 affecting the image acquisition range of the camera 4. At the same time, the image acquisition device further comprises a sonar 5, which is not affected by water quality and can detect the environment around the launched device, covering a larger area, which is beneficial for the staff on the deck to avoid obstacles in time according to the images collected by the sonar 5.
[0042] The launching system further comprises an underwater positioning beacon 20 fixedly installed on the fixed frame 1, which is used to detect the relative position of the fixed frame 1 and the mother ship, facilitating the post-processing of data. The underwater positioning beacon 20 and the transmitting and receiving probe installed on the mother ship perform acoustic positioning, and by superimposing shipborne GPS and compass data, the latitude, longitude, heading and water depth data of the system can be obtained in real time.
[0043] Further, the launching system further comprises a height monitoring device 30 fixed on the fixed frame 1, which is used to monitor the distance between the fixed frame 1 and the seabed, and transmit the distance information to the control unit to prevent the fixed frame 1 from colliding with the bottom. Specifically, the height monitoring device 30 is internally provided with an AHRS sensor (attitude & heading reference system), which can compensate for three-dimensional attitude parameters and provide real-time height values and attitude data. After the bottom sitting attitude is normal, the launched device is launched.
[0044] The launching system can realize efficient, stable and visual launching of the launched device by integrating the image acquisition device, the sonar 5, the underwater positioning beacon 20 and the height monitoring device 30 on the fixed frame 1, so as to accurately launch the launched device to the specified position, improve the success rate of the launched device recovery and the authenticity and reliability of the collected data, and improve the quality of the collected data.
[0045] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
